This invention relates to ineans for supporting detachable barriers between Vhigh tension conductors and apparatus in electric power plants andl the likefand has for its principal object the provisionot anchor strips in the walls et Ythe building cofistructed and arranged to readily support detacliable electric'barriers atany tiine alter the building has been erect1-d.

'ln infy companion application, Serial No. 684,753, have disclosed prererred constructions oit detachable electric barriers `for use between high tension conductors and electiical apparatus, `but in practice have Jfound that the usual wall construction of electric power houses, ubstations, etc. are not arranged to conveniently receiv such electric barriers, and it has been found necessary to design special-anchor strips to be iinbedded in the walls to provide a' foundation for the mounting otiny improved barriers. The present application*discloses such anchor strips, and the preferred ineans of securing thein within the brick and concrete walls usually einployed in 'constructing buildings adapted to house high tension electrical apparatus.

A further object of iny invention is the provision of an anchor strip adapted to be secured within a building wall with its iiiner tace substantially flush with. Vtlieinnei" 'ac'c of the wall, andliaving agroovel oit suil'icient width to receive the 'rear portions of il atacliable electric barriers, socket blocks iinbedcd withiiithe anchor strips in position to receive the bolts or other scour? ing nieans util'ired torifastening the barriers upon tlin anchor strips. y f

vA further object oit` liny invention istlie construction of a wall for buildings housing high tension electric conductors and appa-" ratus wherein a plurality ot grooved anchor strips are secured at predetermined distances with their inner faces substantially kflush with the inner laces 'of the wall wliereb4 j detachable electric barriers inay be conveiiiently fastened to Aand removed troni the wall whenever desired. Y

electric power plant is shown by Way ot eiainple because there are located electrical apparatus and conductors adapted to carry: high tension loadsand, accordingly, detachsectionalV view through' the disclosure in' ing vertical electric is 'an elevation'oic the disclosure inv tail cross sectional view, takf ineinbei'sutilized for holding theini Fig. ll) .is a. detail verticalsection,through able barriers are particularly useful therein.

' It is to be understood, however', that the present invention is also useful in other locations, such as electrical substations, and in fact wherever' high tension conductors or apparatus are installed. y

v`In Figs. l and Q a 4plurality of electric apparatus 8 and bus bars 9 are separated by vertical barriers 1,0y so as to isolate the several electric members, and also to insulate them against possible arcing. Each barrier is formed of a plurality of demountable Y sections 11 formed of fire-proof as Well as electric insulating materials, and arranged to be detachably secured to a horizontal or vertical portion of the power plant, such as in Figs. 6, 8 rand 11 With spaced front and rear Walls and a keyhole slot 16 arranged in the front Wall to permit the ready insertion n of the head of the bolt`13 through the larger portion ofv the slot and the locking ofthe bolt Within the socket block When the bolt is moved into Vthe narrower. portion of the slot 16. The socket blocks 14 are preferably` imbedded in the anchor strips 15 Withtheir inner faces substantially flush with the bottom Wall of the Agroove 17 formed in the front face of the anchor strip, substantially as shown vFigs. 6 and 7 If desired a plurality of projecting members 18 may ext tend-'from the rear face ofthe socket block 14 so as to firmly fasten the socket blocks Within the anchor strips.

The anchor strips 15 are preferably formed of concrete or other moldable material, with a depth substantially equal to the depth of one rowv of bricks in a brick Wall. The sides of the anchor strips may be tapered tofacilitate the locking of the strips withinv a brick'or concrete Wall, and ifA desired a plurality of projecting members 19 may have one of their extremities imbedded VWithin the strips 15 with pins 2O passing through apertures in' the imbedded ends of the projections 19V serving to4 more firmly loc-k the projections Within the strips 1,5. The portions of the projections 19 not imbedded Within the strips 15 are adapted to extendintothe Wall so as to aid in securing the strips 15 within the wall, and with this end in ,View the free extremities of the projections 19 may be angularly disposed to the vcentral portion of the projections.

The inner faces of the anchor strips 15 are preferably arranged substantially flush with the inner faces of the Walls in Which the strips are imbedded, and the grooves 17 are preferably arranged substantially cen trally between the side edges of the anchor strips 15 With their 'bottomWall spaced a suitable distance from the inner face of the anchor strips. The anchor-strips are preferably molded in suitablev lengths with the socketv blocks, 14 spaced at predetermined intervals upon and lightly secured to one face ofthe mold during the molding operation, the mold face being then stripped off so as to leavethe socket blocks imbedded. ln pouring concrete WallsIV may do Without special anchor strips and provide only a board of substantially the dimensions of the groove desired, and lightly fasten to the board the desired socket blocks at predetermined intervals. The board, accordingly, acts as a form for the groove during the molding of the concrete Wall and holds'the socket blocks 14 in their desired positions with their slotted faces substantially flush with the bottom Wall of the grooves. Then after the Wall has set, the boards maybe removed from the strips, leaving the socket blocks 14l imbedded at their Vdesired positions.

In constructing brick Walls of a power house, etc. in accordance with my invention the anchor strips 15 are positioned at spaced intervals vertically and horizontally, asre-V quired, the bricks being laid around the strips 15. The projections 19 extending from the rear face ofthe anchor strips as. Well as the tapered side Walls ofthe anchor strips serve to securely fasten the strips 15 Within the Wall.

The spacingfof the anchor. strips 15 Within the Wall may be in accordance with the de# sired location lof electrical apparatus, conductors, etc., or they maybe spaced at regular intervals'to permitv ready change of location of electrical apparatus, conductors, etc. as desired after lthe building'is constructed.

When it is desired to position the barrier sections 11 upon the anchor strips 15 the elongated bolts V13` are positioned in the apertures 12 of the barriers and the heads of the bolts passed through the slotted socket blocks 14. The rear portions of the barrier sections are then positioned Within thegrooves of the anchor strips, and nuts 13a threaded upon the bolts and turned until the barriers are secured in place. The sides of the grooves 17 serve tosupport the sides of the barrier sections.

`When horiz'ontalelectric barriers 11a are utilized, it is preferredto havey the-grooves 17a in the anchor strips 15 ofgreater Width than the, grooves 17 used for receivingv the vertical.barriersections 11, and the rear por! tions ot the horizontal barrier sections 1la are provided With a reinforcing portion 1lb (note Figs. 9 and l0) adapted to brace the barrier sections While they engage the anchor strips 15. The widened rear portions of the horizontal barrier sections lla are adapted to lit Within the widened grooves 17a of the anchor strips, and the boltslZ for securing these barrier sections in position pass through the upper portion of the barrier sections substantially as shown in Fig. 10.

Vfhile it will be apparent that the illustrated embodiments of my invention herein disclosed are Well calculated to adequately i'ulill the objects and advantages primarily stated, it is to bevunderstood that the invention susceptible to variation, modification and cl'iange Within the spirit and scope of the subjoined claims.
